How many days do you serve in the state of Virginia for a misdemeanor?

If you are found guilty of a misdemeanor larceny in the state of Virginia and sentenced to 360 days with 240 days suspended, then how much of the 120 days (360-240=120) would you have to do? Would you do all of the 120 days or only half, 60 days, since it is a misdemeanor?
